Abstract

To be installed at any latitude from Northern and Southern Hemisphere, a solar tracking mechanism must perform the necessary angular strokes according to the latitude. For a dual-axis solar tracking system azimuthal type, the angular stroke limits depend on the latitude φ and Earth declination angle δ. In the paper, the analytical and graphical dependences for altitude (α) and azimuth (ψ) angles are detailed. Daily variations, maximum daily values during a year for different latitudes in the Northern and Southern Hemisphere and the yearly limits by max/min values at all latitudes for altitude and azimuth angles are calculated and presented in the paper. Based on these variations and limits, the mechanism type (linkage, gears, cams etc.) and the appropriate control algorithms can be selected.
